Board was running alright, and I think I might have used IRC48M as MCG external reference clock. The program crashed and now I'm unable to flash the new application on board.
I'm still able to upgrade the OpenSDA Bootloader firmware, and access MSD flash programmer. But not able to flash the code. Tried this with blhost, KinetisFlashTool, and KDS3.0. Every time initial ping to board seems to fail.
What could be the work around for this issue?
